注釈

このコンストラクターは、 CipherReference 暗号化されたデータを指す Uniform Resource Identifier (URI) を使用して オブジェクトを作成します。 次に、 オブジェクトを使用して、 オブジェクトの参照情報を CipherData 提供します。

URI を使用して、暗号化されたデータを含む XML ファイルを指定できます。 次に例を示します。

String uri = "http://www.woodgrovebank.com/document.xml";

部分 URI を使用して、XML ドキュメントの一部のみを暗号化するように指定することもできます。 たとえば、次の XML コード例に示すように、document.xml という名前の XML ドキュメントに 2 つの MyForm 要素が含まれているとします。

<MyForm Id='Form1'>

<! -- Form data here -->

</MyForm>

<MyForm Id='Form2'>

<! -- Form data here -->

</MyForm>

では、次のような URI を使用してコンテンツ Form2 のみを暗号化できます。

String uri = "http://www.woodgrovebank.com/document.xml#Form2";

CipherReference(String, TransformChain)

CipherReference.cs

指定した URI (Uniform Resource Identifier) および変換チェーン情報を使用して、CipherReference クラスの新しいインスタンスを初期化します。

public CipherReference (string uri, System.Security.Cryptography.Xml.TransformChain transformChain);

new System.Security.Cryptography.Xml.CipherReference : string * System.Security.Cryptography.Xml.TransformChain -> System.Security.Cryptography.Xml.CipherReference

Public Sub New (uri As String, transformChain As TransformChain)

パラメーター

uri

暗号化されたデータを指す URI (Uniform Resource Identifier)。

transformChain

TransformChain
